The mathematical model that is based on this assumption have shown the good agreement with the experimental results, particularly, it allows to predict the non-monotonies of the spatial distributions of Cu+ and Cu2+ ions in the crystal. The design of the 8-channel optical multiplexor and the notch filter based on the ring resonators on the waveguide 'lithium niobate on isolator' structure.5481 Product Description popup.authors Сугак Дмитро Юрійович Убізський Сергій Борисович Яхневич Уляна Володимирівна popup.nrat_date 2020-04-02 Close
